Resurgent Chelsea have risen to fifth in the Premier League after sealing a third straight win under Thomas Tuchel at Sheffield United.
The Blues now sit just one point adrift of fourth-placed Liverpool - who were brushed aside by dominant leaders Manchester City earlier on Sunday - after their impressive start to life under Frank Lampard's successor continued at Bramall Lane.
Meanwhile, an 18th League defeat of the season already leaves Sheffield United rooted to the foot of the table and 12 points adrift of safety.
Chelsea led 1-0 at the interval after a quiet first half in South Yorkshire, with Mason Mount brilliantly sweeping home a precise cut-back from the impressive Timo Werner, whose goal drought goes on despite a far more confident display.
However, Tuchel's men received an early let-off when Oliver Burke fired into the side netting with only seconds on the clock and a Sheffield United penalty awarded for Ben Chilwell's clumsy foul on Chris Basham was overturned by VAR after the Blades defender had strayed offside.
A calamitous own goal from Antonio Rudiger after some miscommunication between the German defender and goalkeeper Edouard Mendy then saw the hosts equalise, but Chelsea quickly restored their lead after Werner seized on a woeful pass from Kean Bryan and was brought down by goalkeeper Aaron Ramsdale.
Italian midfielder Jorginho brought back his familiar hop and skip routine before dispatching what proved to be the winning goal from 12 yards.
